Tax Information

Businesses with GST turnover of $75,000+ must register for GST and issue tax invoices. GST is 10% on most goods and services. Tax invoices under $1,000 have simplified requirements. Over $1,000, the buyer's ABN must be included.

Industry context (2026)

Australian Tax Invoice requirements (per ATO) for sales over AUD $82.50 incl. GST: include 'Tax Invoice' as a heading, supplier identity (ABN required), invoice date, brief description of items, GST exclusive amount per line + GST amount + GST inclusive total. GST is 10% standard with limited exemptions. ABN registration mandatory for businesses turning over AUD $75K+ annually (or AUD $150K+ for non-profits). PEPPOL e-invoicing optional but increasingly required by federal government suppliers.

Worked example

Liam O'Connor runs a Sydney-based IT consulting firm. April invoice for a Melbourne client itemizes: 'IT consulting retainer — April (40 hrs @ AUD $180) — $7,200', 'On-site implementation (April 22, 8 hrs @ $200) — $1,600'. Subtotal $8,800. GST @ 10% = $880. Total $9,680. Includes: Liam's ABN (12 345 678 901), business name, sequential invoice number (TAX INV-2026-0042), client's billing address, ABN if registered, payment due Net 30 from invoice date. Quarterly BAS (Business Activity Statement) lodgement for GST remittance.

Common mistakes to avoid

Missing 'Tax Invoice' header

ATO requires the words 'Tax Invoice' on every invoice over AUD $82.50 incl. GST. Without it, the document is treated as an informal receipt — your client may not be able to claim GST credits.

Not including ABN

If your supplier doesn't include their ABN, your client must withhold tax at the highest marginal rate (47%). Always include ABN; verify your client's ABN via ABN Lookup before B2B sales.

Charging GST when not registered

If your business turns over under AUD $75K and isn't registered for GST, you cannot charge GST. Doing so anyway is illegal and exposes you to ATO penalties.

Quarterly BAS deadline missed

GST-registered businesses must lodge quarterly BAS within 28 days of quarter end (special rules apply for some businesses). Late lodgement triggers escalating ATO penalties.

Invoicing Tips

  • 2Label the document 'Tax Invoice' if you're GST-registered
  • 3For invoices over $1,000, include the buyer's ABN
  • 4Clearly show whether amounts are GST-inclusive or GST-exclusive

Frequently Asked Questions

What must an Australian tax invoice include?

An Australian tax invoice must include: the words 'Tax Invoice', seller's ABN, invoice date, description of goods/services, GST amount (or a statement that the total includes GST), and the total price. For invoices over $1,000, the buyer's ABN and address are also required.

When do I need to register for GST in Australia?

You must register for GST if your annual GST turnover is $75,000 or more ($150,000 for non-profit organisations). You can voluntarily register below these thresholds if you want to claim GST credits.

Can I invoice without an ABN?

You can issue an invoice without an ABN, but the payer may be required to withhold 47% of the payment under the no-ABN withholding rules. It's strongly recommended to obtain an ABN before invoicing.
